Title: Image forming device
Inventor: NAKAMURA MINORU
IPC: G03G21/00
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent image quality from the first copying processing even when an energy saving mode is set immediately after the rising by releasing the inhibition of the control of an energy saving control means when the temperature of a lower roller rises to a temperature required for fixing. SOLUTION: Energy saving control is inhibited until the temperature of the lower roller rises to a temperature required for fixing. When power is supplied, a CPU 371 starts processing and upper and lower heaters 32 and 34 are started so that the heating of the upper and lower rollers may be started. When the temperature of the upper roller attains 200 deg.C, for example, an upper warm-up flag is turned on and an energy saving timer 376 is started. When the length of a standby time becomes 15 minutes from this point of time, whether the energy saving mode should be set is judged. The temperature of the lower roller is still 80 deg.C, for example, at this point of time and the temperature is monitored in a fixed cycle while continuously heating the lower roller.  In the case of satisfying two conditions that the standby time becomes equal to or above 15 minutes and that the warm-up of the lower roller is finished, the CPU 371 turns on the energy saving mode flag.

Title: Antenna system
Inventor: SHIMAWAKI YUTAKA
IPC: H01Q19/18
Filed: 1988-05-30
Abstract: PURPOSE:To achieve desired antenna characteristics without modifying the mirror surface of a main reflecting mirror by providing one of plural converging reflecting mirrors between a primary radiator and auxiliary reflecting mirror and modifying the mirror surfaces of two reflecting mirrors of the auxiliary and converging reflecting mirrors. CONSTITUTION:The mirror surfaces of the auxiliary reflecting mirror 2 and one converging reflecting mirror 4 are modified so that their orbital plane aperture distributions (a) can gradually decrease in the radial direction from the center to the periphery of the main reflecting mirror 1 and orthogonal plate aperture distribution (b) can be uniform. As a result, the orbit plane radiation pattern (c) in the radiation pattern becomes a low-side lobe. Moreover, since the uniform aperture pattern is maintained in the orthogonal plane, this antenna is high in efficiency. Since the mirror surfaces of the two of the reflecting mirrors except the main reflecting mirror are modified so that the orbital and orthogonal planes can have different aperture distributions in such way, an antenna system which is high in efficiency and has axial-rotion symmetrical low-side lobe characteristics can be obtained without modifying the mirror surface of the main reflecting mirror.

Title: Organic waste treatment equipment
Inventor: UEDA MASAKO
IPC: B09B3/00
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain good quality compost having a high decomposition rate by inhibiting the transfer of undecomposed matter to the downstream side. SOLUTION: In this equipment, the inside of a fermenter 1 is divided into plural sections and a material under fermentation is transferred to a final section on the downstream side of the fermenter 1 through the other sections while successively overflowing them. At this time, the transfer rate of the material under fermentation to the downstream side is controlled by detecting the weight and volume of compost in the fermenter 1, the feed rate of organic waste and the load of a driving means 13, to control the rotational direction, rotational speed and operating time of an agitation means. Since the residence time required for fermentation can be secured even at the time of causing any change in load or in waste quality, good quality compost that is dry, granular and easily handleable can be obtained.

Title: Composite type piezo-electric band pass filter
Inventor: SAITOU TAKU
IPC: H03H9/56
Filed: 1983-07-22
Abstract: PURPOSE:To improve the freedom of design at a filter characteristic by displacing a part of plural multimode/monolithic piezo-electric resonators by a Jaumann circuit using single mode/monolithic piezo-electric resonators. CONSTITUTION:In a band pass filter using double mode resonators Q1, Q2, etc. and having 75MHz center frequency and 57KHz and 29KHz band width respectively, the double mode resonator Q2 can be formed, but the Q1 is reduced at its interval between electrodes and it is difficult to realize the Q1 because of the restriction due to the magnitude of an electricity/machine coupling factor. Therefore, the resonator Q1 which is difficult to realize out of the double mode resonators Q1 and Q2 is displaced by the Jaumann circuit using single mode resonators Q3, Q4. Consequenetly, the freedom in the design of the filter is improved, its attenuation can be sufficiently sectured and its production cost and capacity is reduced.

Abstract: PURPOSE:To continue a heating operation, by controlling combustion output so as to obtain a set room temperature if an ionic current is not lowered even after the lapse of a predetermined period in the case where the combustion condition is set to a predetermined fixed level in response to a decrease in the ionic current. CONSTITUTION:When a combustion flame is stable, an ionic current is sampled by an ionic current detector 1, and a first detection level D and a second detection level C are automatically set in a controller 2, based on the ionic current I. If it is judged by an ionic current discriminating means 21 that I<D, a CPU 22 operates a combustion output varying means 24 to bring the combustion output to a predetermined condition, generally increase the combustion output to a maximum combustion condition, and sets a timer 23 to start counting a predetermined period of time tS. When the condition I<C is satisfied, the controller 2 stops the operation of a heater, and turns ON an alarm lamp 4 for alarming. If the condition I<C is not obtained even after the lapse of the predetermined period tS, a combustion control mode is restarted in which the CPU 22 operates the combustion output varying means 24 to control the combustion condition while detecting the current room temperature by a room temperature detecting means 26.

Filed: 1983-07-26
Abstract: PURPOSE:To enable an off-quality oil containing highly hard impurities to be used, by using a quenchable carbon steel and alloy steel for a plunger of a jerk type injection pump, coating it with a highly hard material, and then quenching locally the abutting surfaces fo flanges. CONSTITUTION:A plunger 3 is coated with a highly hard material such as TiC by chemical vacuum deposition, use is made of a quenchable carbon-containing steel and alloy steel, and the two surfaces of a rotating flange 32 that abut against the fork section 61 of a pinion 6 and the upper and lower surfaces of a driving flange 33 that engage with a sliding cylinder 7 and a spring bearing 9 are locally quenched. Thus as the plunger surface is coated with a highly hard material such as TiC or the like, if a fuel contain hard foreign matters, the plunger surface is hardly damaged. Further as the coating by vacuum deposition can be made very thin, if the accuracy of the stock has been increased, lapping or the like after the vacuum deposition is unrequired, or if lapping is carried out, since its period is short, a plunger having highly hard surfaces can be obtained inexpensively.

Title: Fuel injection amount controller of diesel engine
Inventor: KIZAKI KANJI
IPC: F02D1/02
Filed: 1991-06-06
Abstract: PURPOSE:To prevent increase of smoke due to unnecessary increase of a fuel injection amount while maintaining engine failure prevention function. CONSTITUTION:Fuel injection into a diesel engine 2 is controlled by computing the required amount of fuel injection which corresponds to the operation condition of the diesel engine 2 with ECU71 and driving and controlling a fuel injection pump 1. When the number of revolutions of engine is smaller than the predetermined small number of revolutions, the result of computation of the amount of fuel injection with ECU71 is compensated by the increased amount. When the result of detection of a car speed sensor 77 is higher than the predetermined low car speed, compensation of the increased amount of fuel injection with ECU71 is restricted (inhibited). Thus, engine breakdown is prevented by the compensation of the increased amount of fuel injection when the diesel engine 2 rotates at a low speed. Also, when car speed is higher than the predetermined low car speed, the compensation of the increased amount is restricted and unnecessary incerase of the amount of fuel injection is not done, even if the number of revolutions of the diesel engine 2 becomes small.
